Really shitty weed that comes from Mexico or some other place like that. It's dehydrated and stored in kilo bricks for travel, and when the dealer hits you up he just breaks a chunk off and weighs it out. It is usually only 5-10% THC.

All the little goth kiddies here be smoking that brick weed, but we got some fire ass Mauwie Wowie green.

A type of cannabis product: female marijuana plants that have been dried and pressed into bricks or blocks for transportation or preservation.

Usually refers to female marijuana plants that have been cultivated outdoors in commercial quantities using basic agricultural techniques. This method of production results in low THC content and the presence of numerous seeds due to pollination by any male plants that are present.

Often originates from, and uses varieties of marijuana (Indigenous Land Races, or ILRs) indigenous to, Mexico, Jamaica, Thailand or South Africa, for reasons relating to location, climate and cultural attitudes to marijuana use and production.

Popularity and use vary geographically: in countries of origin, this kind of weed, sometimes loose and unpressed, is the staple marijuana product. In the affluent markets of North America and Europe, more powerful, higher quality, locally grown sensimilla (lit. 'seedless') and hashish are favoured. In hashish producing countries (Morocco, Afganistan, Nepal, India) hashish is the staple form of marijuana.

Well-known varieties of brick weed include:

Thai Sticks - Thai, often wrapped round a stick and soaked is cannabis oil for added potency)
Acacpulco Gold - from the Acapulco region of Mexico. Very popular in the US in the 60s and 70s, subject of the cult documentary 'Acapulco Gold' (1973).
Durban Poison - South African
Swazi - from Swaziland, South Africa
Jamaican

Low-quality marijuana, usually grown outdoors, with seeds, in Mexico. The Mexicans smuggle it to the US in highly-compressed bricks, hence the name. Brickweed only refers to the way it was packaged, and there can be such thing as good brickweed, but it's usually a bad thing.

very badly grown weed smuggled from mexico. it is compressed into a "brick" to make it easier to smuggle. contrary to popular belief, brickweed is always shitty weed but only because it was grown wrong. mexican brickweed can be very dank if grown right. infact, most of the popular strains of today have mexican genetics in them.

I bought some shitty brickweed but I got some good seeds from it that I'm going to grow.
